My husband put this together by himself, I just helped lift the twin bed on top of the full. He spent an hour or so each day for a weekend on it, and that was it! My toddler loves it right now. (We’re going to block the steps at night so she can’t climb up when we’re not there, but during the day she gets up and down no problem.) It’s very sturdy. I love the rails on the head and foot of the full bed, and the shelves for storage! I read in some comments people complained of a smell. For us it was nothing you wouldn’t get opening any new furniture. If you can, set it up a couple days before you’re actually going to use it and let it air out in the room and then it’s no problem. We actually got directions to the wrong bed included in the package, but we called Wayfair’s number and the lady emailed us the correct directions that very minute so it wasn’t a big deal. We are very happy with it!
